Best Stainless Steel Garbage Disposals

Best Stainless Steel Garbage Disposals

You came here looking for stainless steel garbage disposals. right?

But do you know that there are no disposals made 100% of stainless steel?

That’s right.

If a manufacturer says his garbage disposal is made of stainless steel it simply means that its grinding chamber, as well as grinding components, are made of stainless steel.

Then why the big fuss?

Using stainless steel gives some benefits. As the name says it is stain ‘less’. It is resistant to corrosion and stain. The disposals made of stainless steel are expected to be last much longer.

Stainless steel vs galvanized steel

For those not familiar with metallurgy, there are different types of steels, but only two are relevant to us here, and they are Stainless steel and galvanized steel.

Steel is an alloy of carbon and iron.

When you add a bit of chromium to steel(11% to be exact), it becomes stainless steel.

When you dip steel in molten zinc, it gets a zinc coating. Both together is called galvanized steel.

The grinding chambers of most garbage disposals are made of either galvanized steel or high-quality plastic. But all their grinding components are stainless steel.

Then what disposals qualify to be called stainless steel disposals?

Well, generally stainless steel garbage disposals are those disposals whose grinding chamber, as well as grinding components, are made of stainless steel.

Stainless steel garbage disposals are very resistant to corrosion and hence they are durable. But they are also costly. So those disposals which are made of stainless steel are usually the top-end models, and so far only the Evolution series by InSinkErator have them.
